No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
When chalk powder is mixed with water, it forms a suspension. In a suspension, the particles of the chalk powder are not dissolved in the water but rather dispersed throughout, giving it a cloudy appearance. A colloid would involve smaller particles that are evenly dispersed and do not settle out over time.
Hot chocolate is a colloid. It is a mixture where small particles of chocolate or cocoa are dispersed throughout a liquid (milk or water) to form a stable mixture.
When chalk (the mineral) dissolves in water, it's called "limewater".
Milk is a common example of a colloid. It consists of small particles of fat suspended in water, creating a colloid mixture.
Chalk is a compound composed mainly of calcium carbonate. It is typically found in a solid form, making it a heterogeneous mixture with various particles dispersed throughout.

Chalk and water do not form a colloid; instead, they create a suspension. In a suspension, solid particles (like chalk) are dispersed in a liquid (like water) but can settle over time. Colloids, on the other hand, consist of smaller particles that remain evenly distributed and do not settle out. Therefore, while chalk in water may appear mixed initially, it is not a true colloid.

A colloid is a mixture that appears to be a solution but it is actually a mechanical mixture. Two examples of a colloid are : MILK and STARCH DISSOLVED IN WATER.
This is a suspension.
To separate salt from chalk, you can dissolve the mixture in water. Salt is soluble in water while chalk is not. After dissolving, you can filter the mixture to separate the insoluble chalk from the salt solution. By evaporating the water from the salt solution, you can obtain the salt crystals.
Vodka is a solution, not a colloid. It consists primarily of water and ethanol, where the ethanol is completely dissolved in the water, forming a homogeneous mixture. In a colloid, the particles are larger and do not fully dissolve, leading to a mixture that can scatter light, which is not the case with vodka.
The Answer Is Colloids!! Lizzpoo$$

Urea solution is not a colloid because it is a homogeneous mixture where the urea molecules are uniformly dissolved in the solvent, usually water. In a colloid, the particles are not dissolved but are suspended within the solvent, resulting in a heterogeneous mixture.
Well they are the same thing because a solution is a type of mixture. If there had to be a difference a colloid solution is when particles are mixed as a colloid in water but a colloid mixture could be anything: a gas colloid, a liquid colloid or a solid colloid. Or any of those three mixed together! It is complicated but basically the difference is that one is particles spread thought mixture and one isn't. Hope it helps :)
Though fog is a colloid, many consider it to be a heterogeneous mixture of water and air.
